Dual Layer DVD Layer Break Error - Advice Needed

[pjcallaway]

Hi All,

 

I'm new to the ImgBurn forums although I have been browsing for a number of years trying to keep pace with the information and technology. You guys really know your stuff!

 

Back at the end of 2007 I created a DVD of a theatre production my wife was in, with some special features etc, and burned it onto a DL disc. The method I used was:

 

1. Create the media using Sony Vegas (export the video and audio files)

2. Build the DVD in Sony DVD Architect (export the prepare files configured for a DL DVD)

3. Use ImgBurn to create the 8MB image file

4. Burn the file to the DVD using ImgBurn

 

I let ImgBurn select the burn speed and layer break settings automatically (don't now enough to fiddle) and I always verify the burn once complete. I used a Phillips drive to burn the discs having verified it can handle DL burns (don't have the drive specs but can provide if needed). I researched the media very extensively and bought Verbatim's (Disc ID MKM-001) so I know I have the best discs. After a couple of coasters everything settled down and I successfully produced around 30 copies of the DVD for the cast and crew that played perfectly.

 

Fast forward to today, and the stock of 6 or so DVDs I have left are all reporting errors at the layer break, and I've had one person contact me recenty to say the same. Attached is the log of the scan I have performed on one of the DVDs. Please note that the drive I've used to scan is not the same one I used to burn the disc, and I did not verify against the image file this time (although I did when I originally burned the discs).

Basically my question is what has happened? Have the discs degraded over time? Was the original burn not quite successful (unlikely as they all verified and played fine after burning)? I'm at a total loss to explain this and am not looking forward to potentially having to replace everyone's DVDs. And given that the discs were bought nearly three years ago, even if I got a dodgy batch I'm sure Verbatim will have nothing to do with me.

 

Any help/advice/analysis would be greatly appreciated.

 

 

Thanks,

Maybe the drive you're using there just isn't as good at reading as the one that burnt the disc?

 

You should also consider that your burner might not have done a great job in the first place.

 

There a pretty wide scope between a good burn and one that fails to read. You could have been right on the (good!) edge of a 'failure to read' when you first burnt them. 3 years down the line, the discs might have deteriorated (I believe where and how you store them can make a difference) and now they're just over the (bad) edge.

Hi,

 

Thanks for the response. I've tried the DVD in the same drives as I did originally when they were burned so I think it is more likely DVD degradation rather than drive degradation (I do clean the lenses from time to time).

 

Other than "wait and see" how else can you tell if the drive has done a bad job of burning? Researching my drive it is (was at the time) meant to be quite a decent device. Given that I've gone for pretty much top shelf on every item/process I am quite peeved that this is the result. The drive is a Phillips Optiarc DVD RW AD-5170A if that helps to identify it as good or bad.

 

 

Thanks,

 

Peter

 

Since I still have the original ISO file perhaps I should get another DVD and do a fresh burn. I have updated the firmware on the drive so see if that, and 3 years of DVD technology (and a different batch) makes a difference.

To test the burn quality you'd need something like a LiteOn drive and use Opti Drive Control/DVDInfoPro to perform a disc quality/PIPO scan on it.

 

That's what we do in all the drive/media testing threads.
